Don't format webLinks for parent commits

Post fd6b981437 ("Don't show
PatchSetWebLink for parent commits") the web UI does not use patch
set web links for the parent commits. These are parent commits,
they are not necessarily a patch set under review, and should not
get links formatted by the PatchSetWebLinks.
